PAIENIEUSEP 12 m2 INVENTOR. 61 11 S/m a L/A/ CIGARETTE HOLDER BACKGROUNDOF THE INVENTION Cigarette holders of the type having disposable trapsand filters have subjected the user to having his fingers stained by thetar trapped from the smoke of the cigarette.

The present invention has for its principal object to provide a trap forthe tars of cigarette smoke which is supported within a cigarette holderin such a way as to permit removal therefrom and subsequent dischargewithout the user having to touch any surface having the exuded tarsubstance thereon.

Another object of the present invention is to provide a cigarette holderof pleasing design, one having a easily detached tar trap, and one whichis economical to produce.

A further object of the present invention is to provide in a cigaretteholder a trap for tars,and a cooling device for smoke arranged in tandemrelation to the tar trap, in order that the trap effectuates the removalof the tars of the smoke at a point nearer to the cigarette than thecolling device in order that the cooling device be kept relatively freeof the condensed tar smoke.

These and other objects of the invention will be understood from thefollowing description and with reference to the drawing, in which:

FIG. 1 is a side elevational view of the cigarette holder of the presentinvention, a cigarette being indicated by a dotted line.

FIG. 2 is a central longitudinal sectional view on line 22 of FIG. 1, onan enlarged scale,

FIG. 3 is an exploded view,

FIG. 4 is an elevational view on line 4-4 of FIG. 3,

FIG. 5 is a elevational view on line 5-5 of FIG. 3, and

FIG. 6 is an isometric view of the trap employed in the cigaretteholder.

Referring in detail to the drawing, in which like numerals indicate likeparts in the several views, the numeral l0 designates generally theholder of the invention. It consists in a mouthpiece l2 and a tubularelement l4 spaced axially form the mouthpiece 12.

A center part, indicated generally at 16, includes the sleeve 18provided on the end portion adjacent the mouthpiece 12 with internalthreads 20 receivably engaging threads 22 formed on the adjacent end ofthe mouthpiece 12.

The element 14 is provided on its outer end portion with bore 24 of asize to receive an end portion of a cigarette, as in dotted lines at 26in FIG. 1.

The other end portion of the element 14 has a bore 28 to slidablyreceive one end portion of the sleeve 18. The bores 24 and 28 areconnected by a reduced diameter bore 30 so that the bottom of bore 24 isa shoulder 32 against which the end of the cigarett 26 abuts wheninserted in the bore 24.

The element 18 is provided with a bore 34, in axial alignment with thebore 30, and with a larger bore 36 which receives the body or tar trap38, shown in FIG. 6 removed from the holder 10.

A cooling sleeve 40 having external spiral grooves 42 and ridges 44,shown most clearly in FIG. 3, is slidably received in a bore 46 providedinwardly of the end of the mouthpiece 12 having the threads 22.

The sleeve 40 is provided with an axial bore 48 in alignment with andcommunication with the bore 50 of the mouthpiece 12.

The element 40 has another bore 52 communicating with the bore 48 and ofa slightly larger diameter so as to provide a shoulder 54 against whichrests one end of a compression spring 56 which has its other end bearingagainst one end of the trap 38 so as to force the trap 38 into abuttingrelation with the shoulder 58 formed by the different diameters of thebores 34 and 36 in the element 16.

With reference to FIGS. 4 to 6 inclusive the trap 38, formed of atransparent material such as plastic or the like, is shown to have atapering peg 60 projecting from one end and formed integrally with thetrap 38 which is cylindrical and hollow.

The other end of the trap 38 is closed by a disc 62 having an aperture64 centrally thereof. The trap end having the peg 60 projecting axiallytherefrom is provided with spaced holes 66 arranged about the peg 60 andforming with the aperture 64 a through passage for smoke from thecigarette 26 as indicated by the arrows in FIG. 3.

The trap 38 is also formed on the inside with a tapered boss 68 havingspiral flutes 70 so as to impart a swirling motion to the smoke as thesmoke flows through the trap 38.

In use, the smoke from the cigarette transverses bores 30, 34, aperture64, through the interior of the trap 38 around the boss 68, through theholes 66,and then through the bores 52,48, and 50 successively.

The trap 38 is easily removed after the mouthpiece 12 is unscrewed fromthe sleeve 18 and may be as readily cleaned of any condensate byremoving the disc 62 and rinsing the interior of the trap 38 in runningwater or solvent of the condensate. The trap 38 is of little expense tomanufacture and may be readily discarded if desired.
